Short-term visual performance of soft multifocal contact lenses for presbyopia.
PURPOSE To compare visual acuity (VA), contrast sensitivity, stereopsis, and subjective visual performance of Acuvue® Oasys® for Presbyopia (AOP), Air Optix® Aqua Multifocal (AOMF), and Air Optix® Aqua Single Vision (AOSV) lenses in patients with presbyopia. METHODS A single-blinded crossover trial was conducted. Twenty patients with mild presbyopia (add ≤+1.25 D) and 22 with moderate/severe ...
متن کاملVisual performance with simultaneous vision multifocal contact lenses.
PURPOSE The aim was to assess visual performance after PureVision high addition multifocal contact lens (PM) fitting through contrast sensitivity measured under different illumination levels for both distance and near. METHODS In a cross-over study, 20 presbyopic patients were randomly assigned to PM or spectacles. Near contrast sensitivity was measured with the Vistech VCTS 6500 system. ...
متن کاملPower Profiles of Commercial Multifocal Soft Contact Lenses
PURPOSE To evaluate the optical power profiles of commercially available soft multifocal contact lenses and compare their optical designs. METHODS The power profiles of 38 types of multifocal contact lenses-three lenses each-were measured in powers +6D, +3D, +1D, -1D, -3D, and -6D using NIMO TR1504 (Lambda-X, Belgium). All lenses were measured in phosphate buffered saline across 8 mm optic zo...
متن کاملSwitchable Liquid Crystal Contact Lenses for the Correction of Presbyopia
Presbyopia is an age-related disorder where the lens of the eye hardens so that focusing on near objects becomes increasingly difficult. This complaint affects everyone over the age of 50. It is becoming progressively more relevant, as the average age of the global population continues to rise. Bifocal or varifocal spectacles are currently the best solution for those that require near and far v...
متن کاملThrough-focus visual performance measurements and predictions with multifocal contact lenses
We measured high-contrast visual acuity (VA) and 12c/deg contrast sensitivity (CS) through-focus functions (TFF) of four eyes of four cyclopleged subjects in three conditions: naked eye, with a center-distance and center-near Proclear(R) multifocal addition 2D contact lens. In all conditions, an adaptive optics system statically compensated the astigmatism of the subject's eye alone. Multifocal...
